DiKsa [7]

Answer:

A = 2200x - 2x^2

Step-by-step explanation:

Let's x be the length of the side that is NOT the same as the side along the river (or in opposite). From the fencing perimeter of 2200ft we can calculate the other side y of the rectangular:

y = 2200 - 2x

The area A of the pen would be the product of the 2 sides

A = xy = x(2200 - 2x) = 2200x - 2x^2

g100num [7]

Answer:

{f}^{ - 1}(x)  = 2x + 8

Step-by-step explanation:

f(x) =  \frac{x}{2}  - 4 \\ \\  y = \frac{x}{2}   - 4 \\ \\ y =  \frac{x - 8}{2}   \\  \\ x = 2y + 8 \\  \\  {f}^{ - 1} (x) = 2x + 8

Jobisdone [24]

oof

remember some rules

(a/b)(c/d)=(ac)/(bd)

\frac{x^a}{x^b}=x^{a-b}

x^0=1

(x^a)(x^b)=x^{a+b}

x^{-a}=\frac{1}{x^a}


\frac{(7^{-3})(7^{-2})(2^0)}{(7^{-1})(7^{-4})(2^3)}=

\frac{(7^{-3-2})(2^0)}{(7^{-1-4})(2^3)}=

\frac{(7^{-5})(2^0)}{(7^{-5})(2^3)}=

(\frac{7^{-5}}{7^{-5}})(\frac{2^0}{2^3})=

(7^{-5-(-5)})(2^{0-3})=

(7^0)(2^{-3})=

\frac{1}{2^3}=

\frac{1}{8}
